Answer:
628.32 feet
Step-by-step explanation:
The SkyView Ferris wheel is 200 feet in diameter.
A) The distance around the Ferris wheel would be the Circumference of
the Ferris Wheel.
B) The formula for circumference is given by
circumference = 
× diameter
C) the distance traveled in one rotation is the length of the circumference
given by circumference = × diameter
∴ circumference = 3.14159 × 200 feet = 628.32 feet.
Answer:
The mean life time of the bulbs is approximately 739 hours
Step-by-step explanation:
Here, we want to calculate the mean life time
From the question, 95% of the bulbs die before 920 hours
What this mean is that the probability that a bulb will die before 920 hours is 95% = 95/100 = 0.95
Now, we need the z-score that is exactly equal to this value
Using the standard normal distribution table, the z-score corresponding to this probability value is 1.645
Mathematically;
z-score = (x-mean)/SD
In this case, x is 920, SD is standard deviation which is 920 hours
thus, we have it that;
1.645 = (920-mean)/110
110(1.645) = 920 - mean
180.95 = 920 - mean
mean = 920- 180.95
mean = 739.05
Answer:
2/3
Step-by-step explanation:
(1- (-5))/(2-6)=
(6/-4)=
-3/2
perpendicular means reciprocal so the slope would be 2/3
Volume = Ah
where:
A is area of base
h is perpendicular height
Answer:
x= 0 I believe the answer would be false.
